Product details
A 1.410-inch offset identifies this Wilwood dynamic drag hat. The eight-lug rotor interface needs its specified ring and retention components. Bill Wood founded Wilwood Engineering in 1977, and the manufacturer is based in Camarillo, California. Wilwood designs and manufactures disc brake systems alongside calipers, master cylinders, rotors, fittings, brake lines and valves. The motorsport, street-performance and specialized ranges depend on components selected to work within a complete braking system.
